† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
              2. The package thermal impedance is calculated in accordance with JESD 51-7.

The SN74CBT6800A provides ten bits of high-speed TTL-compatible bus switching. The low on-state resistance of the switch allows bidirectional connections to be made while adding near-zero propagation delay. The device also precharges the B port to a user-selectable bias voltage (BIASV) to minimize live-insertion noise.

The SN74CBT6800A is organized as one 10-bit switch with a single enable (ON) input. When ON is low, the switch is on, and port A is connected to port B. When ON is high, the switch between port A and port B is open.When ON is high or V_CC is 0 V, B port is precharged to BIASV through the equivalent of a 10-k resistor.
